The two NHL ones would involve mostly Canadian railroad trackage, Canada+hockey=not grumpy (not to mention GO slowly buying up the route from CN). However they've called Buffalo-Toronto matchups the "Battle of the QEW", not sure the "Battle of the Oakville Subdivision" has the same ring to it.

Also I didn't know Seattle and Portland both had MLS teams, that was one I thought of but couldn't figure out a sport that would fit. Cool!
